#74 of 102 1-2 minute delay for the radio and air conditioning when start 2004 Sienna
Sep 13, 2011 (11:17 am)
This has happened several times now. We start up the car and everything starts up fine, but our radio and air conditioning doesn't turn on for about a minute or two. We haven't checked the lights or wipers during the delay, but will do so next time. Any ideas as to what could be the problem?
It only happens when the car is started up.
#75 of 102 not your normal start problem?
Oct 25, 2011 (6:58 pm)
1998 toyota sienna, about 220k miles. Intermittently, the van would not start, not crank, no nothing (for the last ~3 mos). Now it's not starting any more at all. Battery is good. Shop says that the starter motor is not getting power, not sure why still investigating... (broken cables?)
Symptoms: Control lights come on when I turn the key, but not the "check engine" light. Also out is the little light circle around the gear you are in (like "P"). Other electrical issues have been creeping up over the years, not sure if related? Driver side power window will sometimes get stuck, have to wait 3-5 minutes and then it will pull all the way up. Light on the speedometer (right side) of dashboard has been out for about 2 years, 12V power connectors (front middle and back on the side of car) will no longer charge reliably, again this is about 2-3 yr old issue, ... The other day I dropped off sth at a friends house, had car idling in driveway and when I shut the tail gate, the motor stuttered and stopped.
It's been a reliable car and I want it back in business! Is this something that a dealer shop needs to look at? Where can I get a wiring diagram? Thanks for your consideration!!!
#76 of 102 12v Power Adapter
Oct 29, 2011 (5:40 pm)
I have a 2006 Sienna. There are two power adapters on the dash and one in the back. One of the two on the dash and the back power adapters do not work. Does anyone know where the fuse is located?

I have the same problem on my 2004 Sienna. Did anyone offer suggestions?
#78 of 102 Replay to Toyotafan86

No one responded. But the Toyota dealership ended up finding it. I don't know the precise relay switch but it was a relay switch under the hood that connected the radio and heat. The crazy thing is just a few weeks ago our dashboard was flipping out. That was another relay switch that needed to be replaced - one that was under the dashboard making a clicking sound.

You're right no one responded.
A switch that connects the radio and heater has something to do with the power adpter?
#80 of 102 Head relay clicking on a 2000 Sienna
Feb 10, 2012 (11:54 am)
There is a continuous clicking sound from my 2000 sienna when it's parked in garage, engine is off, key is out and doors are closed. At the same time I found I can not start the car, and the door light is quite dim.
Later I found the sound is from Head Relay, and if I turn the headlight switch to 'off', the sound will be gone.
What could be the root cause of this? The battery is about 4 years old, and I think it's time to replace, but is the dead battery causing the click, or the click causes the dead battery?
#81 of 102 Re: 2008 Toyota Sienna Radio Volume Issue [druzilla1977]
Aug 13, 2012 (10:44 am)
I have encountered the same issue with my 2010 Rav4. Every now and then, the volume will increase for no reason. The times I have noticed this is when I'm shifting into reverse from being in either Park or Drive. My RAV4 does not have steering wheel controls for the radio, so I'm not sure what might be causing the conflict.
My pre-owned RAV4 was a rental car for a year, so I thought maybe there were some restrictions put on the volume of the radio (as it seems to be fairly quiet even with the volume cranked to 20+). But I find it interesting that there are others out there with similar issues.

replace the starter contacts, no need to remove the complete starter, just the head.

Did you happen to get your Sienna Van left turn issue resolved?? I have a 1998 Toyota Sienna van also and when I turn left the map lights come on, the panel shows door ajar (LED) and if the doors were locked, they become unlocked (click noise). Once you straighten wheel and go straight all becomes normal and map lights turn off, etc. This NEVER happens when turning RIGHT.
Any ideas for fixes out there ??????
